stralloc_ready - provide space in a stralloc
#include <libowfat/stralloc.h>
int stralloc_ready(stralloc* sa,size_t len);
stralloc_ready makes sure that sa has enough space allocated to hold len bytes: If sa is not allocated, stralloc_ready allocates at least len bytes of space, and returns 1. If sa is already allocated, but not enough to hold len bytes, stralloc_ready allocates at least len bytes of space, copies the old string into the new space, frees the old space, and returns 1. Note that this changes sa.s.
If stralloc_ready runs out of memory, it leaves sa alone and returns 0.
1 for success, 0 on memory allocation failure.
